Utica, N.Y. -- Jevon Wameling has pleaded guilty to manslaughter in the disappearance and death of his infant son, whose remains were found in the Mohawk River in September, Oneida County District Attorney Scott McNamara announced Wednesday.

The plea came in Oneida County Court Wednesday morning in front of Judge Barry Donalty, according to McNamara.

Jevon Wameling will receive a 7-1/2 to 15 year prison sentence when he is sentenced on Jan. 30, 2014.

Levon Wameling's body was found Sept. 6 by a state police dive team at the bottom of the river. Authorities have still not said how he died.

The baby's supposed disappearance May 29 led to a summer-long search by law enforcement and the community. Police searched East Utica, the town of Marcy, Barnes Avenue in the city of Utica and an Ava landfill, sometimes with help from volunteers.

Jevon Wameling has given conflicting accounts of what happened to his son.

It took him two weeks to report that his son had gone missing, according to law enforcement.

He initially insisted that the 9-month-old disappeared from his front porch. Jevon Wameling said he left his child unattended for a few minutes in front of his home on Jay Street when he realized he was locked out of his home, police said. He went around to the back of the home to get inside and when he returned to the front of the house, the child was missing.

Then, in a letter to the Utica Observer-Dispatch, Jevon Wameling wrote the baby actually died in his sleep. Wameling admitted he hadn't been honest.

"I had my reasons," Wameling wrote in a single-page note dated Sept. 28. "One of those reasons being that I was scared out of my mind. It's not every day a man like myself find's (sic) his son dead in his sleep and that is 100% the truth."

Additionally, Jevon Wameling was charged with burglarizing his step-uncle's home in Oriskany in September. He is described as broke, unpredictable, addicted to drugs and threatened by drug dealers in court paperwork related to the burglary charge.
